That is, in the present invention, the present invention can be applied if either the left or right or both sides are fixed shelves or fixed walls and there are two or more moving shelves between them. In FIG. 1, W is a wall, F is a floor, and R is a rail.

Each of the above-mentioned shelves 2 to 5 is connected to one of the shelves 2 to 5
On the right or left side of the storage unit in each shelf 1-5,
The moving direction and the moving amount (distance) are controlled so that a passage for entering and exiting articles and the like or a work space S (hereinafter, referred to as a passage S) can be necessarily formed from the front. Although the present invention constitutes an electrically-driven, densely-movable moving shelf apparatus, the present invention has one of the features in the formation of the passage S for each of the shelves 2 to 5, and this point will be described below.

First, each of the shelves 2 to 5 has a position switch 2c to detect the relative position of the adjacent shelves, here, the shelves 1 to 4, that is, whether the shelves are close to or separated from the adjacent shelves. 5c is provided. In this embodiment, the ON state of each of the position switches 2c to 5c indicates close contact with an adjacent shelf, and the OFF state indicates that the position is off.
Here, “close” means that the shelves are in abutting state, and “separation” means that a path S or
This means that a gap having an appropriate width is formed. 5c 'is a position switch for the wall W of the shelf 5.

On the left and right sides of the side plates of the above-mentioned shelves 2 to 5, two left and right instruction switches 6a, 6a, 6b, 6c are provided in order to indicate that a passage S is to be formed between the adjacent shelves 1 to 4. 6b-9a, 9b

In addition, the microcomputers 18 to 21 are provided with a function of exchanging operation mode data held by the microcomputers 18 to 21 by a so-called bidirectional communication method. Here, four shelves 2
Regarding to 5, the equivalent microcomputers 18 to 21 are mounted on each shelf. For convenience of control, one of the microcomputers 18 is set as a main microcomputer, and a plurality of information issued from the main microcomputer 18 is provided. Each microcomputer 18 ~ according to the command
Between 21, the commands indicating the operation modes of the respective shelves 2 to 5 are sequentially supplied to the microcomputers of the adjacent shelves. The other microcomputers 19 to 21 are added to the main microcomputer.
Whichever of the above is selected, there is no problem in practicing the present invention.

The commands issued by the main microcomputer 18 include, for example, the states of the motors 2b to 5b on each shelf, the states of the position switches 2c to 5c ', and the safety bar 10a.
There is an information command issued to confirm the status of the instruction switches 6a to 9b and the status of the instruction switches 6a to 9b. In addition, if a security switch or an object detection sensor for each of the shelves 2 to 5 is provided in the information command, a command for checking the state thereof is set. Therefore, the content of the information command differs depending on the configuration assigned to each of the shelves 2 to 5.

The operation modes of the respective shelves 2 to 5 include:
There are a locked state, a reset state, and a moving state.
Lock commands, reset commands, and movement commands for controlling the operation modes of the motors 2b to 5b, etc., by the microcomputers 18 to 21 of the shelves 2 to 5. There is.

The content of the lock command is different for each factor because the lock mode differs depending on the lock factor. That is, the normal lock when the movement is normally completed, the emergency lock A by operating the emergency stop key during the movement,
An emergency lock B in which a safety bar or the like operates during movement, and a motor lock based on detection of a motor abnormality during movement. The content of the reset command is for releasing the locked state. The move command is issued so that the microcomputers 18 to 21 of the respective shelves 2 to 5 determine the moving direction of the respective shelves 2 to 5 and activate the predetermined motors 2b to 5b in that direction. You.

Now, when the shelves 1 to 5 are in the state shown in FIG. 1, that is, a passage S is formed between the fixed shelf 1 and the shelf 2, and the other shelves 2 to 5 are in a dense state, The operation mode of the motors 2b to 5b is locked, and the pilot lamps 14a
~ 17b is also off. A case where the user forms the passage S between the shelves 3 and 4 in this state will be described below.

First, the user turns on the power supply (not shown) of the entire mobile shelf apparatus of the present invention. At the time of turning on the power of the apparatus, each of the shelves 2 to 5 is necessarily held in the locked state at the position before the power is turned on by the operation of the respective microcomputers 18 to 21, and the main microcomputer 18 is controlled by the microcomputers 19 to 21. Information command is issued. The information command is transmitted in order from the microcomputer 18 on the shelf 2 to the microcomputer 21 on the last shelf 5, and an answer to the information command is returned from the microcomputer 21 on the shelf 5 to the microcomputer 18 on the shelf 2. That is, each shelf 2
The operation modes held by the microcomputers (1) to (5) are sent to the microcomputer on the next shelf as an information answer to the information command, and stored in the microcomputer on the next shelf. As a result, the microcomputers 18 to 21 of the respective shelves 2 to 5 provide the data indicating the status of the shelves adjacent to each other together with the status of the shelves provided with the microcomputers.
Main microcomputer 18 and other microcomputers
The answer information is analyzed from 19 to 21 to determine whether or not each of the microcomputers 18 to 21 has an instruction input of the instruction switches 6a to 9b. In the locked state, the switches are connected to the microcomputers 18 to 21.
There is no input from 6a-9b.

Now, the motor 2b of each of the shelves 2 to 5 shown in FIG.
5b are in a locked state, so that when a path S is to be formed between any of the shelves 2 to 5, the reset key is operated to supply a reset command to the microcomputer of each motor to perform a reset. Must be in a state. In the present invention,
When the movable shelves 2 to 5 are in the dense state of FIG.
A valid reset key indicates that any one of the indicating switches 6a to 9b (any one of them) is kept pressed for one second.
And the microcomputer connected to the reset key holds that one of the instruction switches 6a to 9b has been pressed. This reset input is supplied to the main microcomputer 18 as answer information of the information command. Then, a reset command is issued from the main microcomputer 18 and the motors 2b to 5b of the respective shelves 2 to 5 are operable, that is, they are in a reset state.

In the apparatus of the present invention, each of the shelves 1 to 5
It is desirable that the effective reset key when the passage S is locked in a state where the passage S is formed between them is limited to an instruction switch facing the passage S. This is because it is easy to visually confirm the safety of the passage S. In this case, in order to indicate which of the instruction switches 6a to 9b the valid reset key is, by the pilot lamps 14a to 17b, when the path S of FIG. 2 is formed, the instruction switch 7b or 8a
The pilot lamp 15b or 16a corresponding to is turned on or blinks in green, for example. In the locked state of FIG. 1,
Since the reset key serves as the instruction switch 6a, the pilot lamp 14a is lit green or blinks. In the present invention,
When each of the above instruction switches 6a to 9b is pressed,
In order to indicate that the operation is valid, a small electronic sound is generated from a speaker (not shown). The generation of the operation sound can be set according to the user's preference so that the operation sound is not generated.

In the reset state of FIG. 1, as an example, when it is desired to form the passage S between the shelves 3 and 4 in FIG. 1, either of the indication switches 7b or 8a facing the passage S to be formed is desired. Press one of the instruction switches. Here, when the instruction switch 7b is pressed, the operation becomes an operation of a passage formation effective key (hereinafter, referred to as a passage key), and a signal by this operation is transmitted to the microcomputer 19 connected to the switch 7b.
Formed and held. On the other hand, information commands are sent from the main microcomputer 18 to each microcomputer 18 to
Since the answer information is supplied to the microcomputer 21 and the answer information is returned, it is returned that the microcomputer 19 holds the signal of the passage key.

The main microcomputer 18 issues a movement command to each of the microcomputers 18 to 21 when the analysis of the answer information indicates that the input signal of the passage key has been formed on any of the shelves. Upon input of the movement command, the microcomputers 18-21 of the shelves 2-5 respectively turn on and off the position switches 2c-5c 'of the shelves 2-5 and the instruction switches 6a-9b.
In each of the microcomputers 18 to 21, whether or not each of the shelves 2 to 5 can be moved and the direction in which the shelves can be moved are determined from the state described above.

In the case of this example, the microcomputers 18 to 21 are first connected to the microcomputers 18 and 19 of the shelves 2 and 3 located on the left side when viewed from the path S to be formed (that is, the next path S). , 3 to the left, right side of the shelf 4, 5 microcomputer
20 and 21 determine the directions in which the shelves 4 and 5 should be moved to the right. In order to form the passage S between the shelves 3 and 4, the movable space of each of the shelves is a fixed shelf 1 and a shelf 2
(The microcomputer 18 determines the OFF state of the position switch 2c), so that the shelves 2 and 3 can be moved to the left. , 5 are determined by the microcomputers 18 to 21 to be incapable of moving to the right. FIG.
In the state of the above, the right row of each of the shelves 2 to 5 is not possible, which means that the ON state of the position switches 5c and 5c '
Judge by knowing 20 and 21.

Next, the fact that it is possible to move to the left is shown on shelf 2,
When the microcomputers 18 and 19 determine, the rotation commands (including the rotation direction) of the motors 2b and 3b are supplied from the respective microcomputers 18 and 19 to the motor control units in these microcomputers. on the other hand,
The microcomputer 20, which determines that the shelves 4 and 5 cannot move to the right,
In step 21, no rotation command is issued for the motors 4b and 5b. In the movable shelves 2 and 3, first, the shelf 2 from which the position switch 2c is released receives the rotation command of the microcomputer 18 and the motor 2b starts rotating in the command rotation direction. Start moving to the left. Next, since the position switch 3c is released when the shelf 2 starts moving leftward, the shelf 3 starts moving leftward at that time. Shelf 2
And the shelf 3 move left at a constant speed without being closed by the position switch 3c of the shelf 3 being in contact with the back surface of the shelf 2. In the apparatus of the present invention, the shelves 2 and 3 to be moved are not simultaneously started by the operation of the position switches 2c and 3c and the microcomputers 18 and 19, so that the two shelves 2 and 3 do not start simultaneously. -The starting power required at the time of starting the data is small. On the other hand, the pilot lamps 7b, 8 facing the passage S formed in synchronization with the movement start of the shelves 2, 3 by the operation of the microcomputers 18, 19
a or pilot lamps 6a to 7b on shelves 2 and 3 during movement
Lights red. During this time, an information command is issued from the main microcomputer 18 and the operation mode of each of the shelves 2 to 5 is controlled.
Are always collected as answer information of each of the shelves 2 to 5.

When the shelves 2 and 3 move to the left and the shelves 2 approach the right side of the fixed shelf 1 and the position switch 2c is closed, the motor 2b stops and is locked to lock the shelves 2. Is completed. When the shelf 2 stops, the position switch 3c
Is stopped and the motor 3b is locked in the same manner as the shelf 2. When the movement of shelves 2 and 3 is completed,
The pilot lamps 7b, 8a or the pilot lamps 6a to 7b, which have been lit red by the action of 8, 19, are turned off, indicating that they are locked. When the movement of the shelves 2 and 3 is completed, a new passage S is formed between the shelves 3 and 4 as shown in FIG. 2, and all the shelves 2 to 5 are in a locked state, that is,
The next movement cannot be performed at all unless a reset for releasing the locked state is applied. In order to reset the locked moving device of the present invention in which the passage S is formed between the shelves 3 and 4, the indicating switch 7b or 8a facing the passage S becomes an effective reset key.
The lock state cannot be released unless 7b or 8a is pressed.

In the moving shelf apparatus according to the present invention, for example, while the shelves 2 and 3 are moving, the safety bar, that is, the baggage or the like collides with the safety bar or the intermediate bars 10a to 11b. Any of the switches 10a to 1g linked to the bar
When 1b is turned on, the microcomputer connected to the switches 10a-11b
18 and 19 are in the operation mode of the emergency lock B, and the shelves 2 and 3 which are moving are immediately stopped by the motors 2b and 3b and are kept in the locked state. When the user wants to stop the movement of the shelves 2 and 3 during the movement, the user can press any one of the instruction switches 6a to 9b. This push operation
This corresponds to the emergency stop key operation, and the microcomputer on the shelf having the switch instruction switch first becomes the operation mode of the emergency lock A, which is transmitted to other microcomputers as answer information for the information command. That is, the operation modes of the emergency locks A and B are always used as answer information of information commands issued for data exchange of the respective shelves 2 to 5 as microcomputers of the respective shelves 2 to 5. The lock command is transmitted from the main microcomputer 18 to each microcomputer 18 based on this.
~ 21. Similarly to the locked state at the end of the steady running, the locked state during the movement cannot be restarted unless reset. In this case, the movement is restarted by a passage key operation of pressing the same switch 7b or 8a after the reset by the operation of the instruction switch 7b or 8a facing the passage S being formed.

The basic structure and the operation mode of the mobile shelf apparatus of the present invention are as described above. However, the present apparatus is provided with another configuration which will be described later. .

In the present invention, as an example, the adjacent shelves 1 to 1

Between the shelves 2 and 3
This allows only a specific person to access articles and the like stored in the storage section on the joint surface side of the storage section. Thereby, the storage state of articles, documents, and the like stored in the storage section where the passage S is not formed can be kept secret.

In the case of the above example, the means for obtaining the above functions include, for example, a mechanical structure for holding the shelves 2 and 3 in their joined state, for example, a connecting bar and a chain unlocking mechanism of this bar, In conjunction with the locking of the mechanism, the microcomputer 19 of the shelf 3 is provided with a circuit for setting the input and output terminals to a through state and freeing the output shaft of the motor 3b.

With this arrangement, when the chain unlocking mechanism is in the unlocked state, the operation mode of the motor 3b of the shelf 3 is controlled by the operation of the microcomputer 19 as in the above embodiment. However, when the chain unlocking mechanism is locked, the shelf 3 and the shelf 2 are mechanically connected by a connecting bar, and the microcomputer 19 does not operate and the motor 3b is mechanically free. Therefore, the shelf 3 moves integrally with the shelf 2, and the shelves 2, 3
Can form a confidential storage section on the joint surface of the. In addition,
When shelves 2 and 3 are held in a joined state, both shelves 2 and 3
Indication switches 6a, 6b, 7a, 7b, and pilot lamp
14a, 14b and 15a, 15b are indication switches 6a and 7b, respectively.
The pilot lamps 14a and 15b are operable, and the remaining indicator switches 6b and 7a and the pilot lamps 14b and 15a are kept inoperative by the operation of the microcomputers 18 and 19, respectively. Whether such a security lock structure is formed between the other shelves 1 and 2 or between the shelves 3 to 5 is optional.

Next, in the above embodiment, in order to form the path S between the desired shelves, when the necessary shelves are properly moved, the motors 2b to 5b of the shelves 2 to 5 become It is locked. In order to make the next movement of each of the shelves 2 to 5 in the locked state, the instruction switch facing the formed path S is operated as an effective reset key, and the locked state is reset to reset each motor. The reset state of 2b to 5b, that is, the operable state must be instructed by each of the microcomputers 18 to 21, so that even if a person enters the previously formed path S and is working, it is temporarily safe. is there. However, if the user moves the shelf without resetting the locked state without noticing that the person is in the passage S, the safety bar or the like 10a
It is dangerous to have ~ 13b.

In the apparatus of the present invention, a non-contact type object detection sensor such as an infrared sensor is provided on the front side of each of the shelves 2 to 5, that is, on the side facing the passage S, and the passage S is formed. At the same time, the sensors on the shelves facing the passage are activated, and the activation of the sensors causes
The motors 2b to 5b are interlocked by the microcomputers 18 to 21. Interlock of each motor 2b
5b, the reset operation of unlocking in the above-described embodiment does not become effective, so that the shelf does not suddenly move when viewed from the person inside the passage S, and You can work with peace of mind even if you are there. The interlock can be released by operating a separately provided interlock release switch.

In the apparatus of the present invention, appropriate illumination sources L1 to L5 are provided on the sides of the shelves 2 to 5 where the passages S are formed, respectively, and the illumination sources L1 to L5 are connected to the formed passages S1 to L5. Only those that face are sometimes turned on. The lighting is on the passage S
